An Edge-First Approach to Systematic Trading Research
Summary
This introductory page presents a research philosophy for independent systematic traders: begin by identifying a plausible market edge, then use tools such as backtesting to investigate it. A backtest can show how a set of rules performed historically, but it cannot explain why those rules should continue to work. The suggested research question is who takes the other side of a trade and what motivates them to do so.
The page describes potentially persistent sources of returns as bearing risks other participants avoid or trading around predictable flows. It argues that individual strategies may be small or inconvenient to trade, and that combining several into a portfolio can make them more useful. The author illustrates the pitfalls of excessive optimization and complexity with a personal account of an early strategy that initially performed well but proved lucky. This is an educational overview, not a detailed research procedure: it provides no quantitative evidence, strategy specifications, or risk estimates. The courses, community, and case study mentioned are promotional offerings rather than evidence for the approach.
Key ideas
- A historical backtest measures past rule performance but does not explain the source of returns.
- Research should identify who is on the other side of a trade and why they trade.
- Some potential edges come from bearing unwanted risks or trading around predictable flows.
- Combining several small strategies may produce a more useful portfolio than relying on one.
- Complexity and optimization can produce attractive historical results that fail out of sample.
